Research ArticleOpen accessIn the abstractEnergetic Aspects Related to Heavy Metals Adsorption on the Surface of Volcanic Tuff I. The Influence of Activation Parameters in Cu2+ AdsorptionLeonard Mihaly-Cozmuta, Teodor Visan, Anca Mihaly-Cozmuta et al.The article develops some physico-chemical aspects presented along of copper ions adsorption in treatment of wastewaters using volcanic tuff. In the experiments volcanic tuff from Stoiana Pâglişa (Romania) has been used. Different concentrations of NaCl and HCl solutions were used for activation of tuff. The increase of activation solutions' concentrations indicates an intensification of specific adsorption of copper as consequence … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Gamma Irradiation on the Structure Diffusion Coefficient of Co-Zn Doped FerriteDalal Mohammed HemedaA series of the ferrite system Co0.6Zn0.4MnxFe2-xO4 with (x = 0.7, 0.8, 0.9 and 1) were prepared by general ceramic method. The X-ray diffraction patterns confirmed the formation of the cubic single phase structure. The lattice parameter and the crystal size increased after irradiation which was attributed to the formation of ferrous ions of larger radius than that of ferrous … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Zinc, Cadmium, Lead and Copper in Kakade, Anise, Cumin, Caraway Black Pepper Extracts Using Differential Pulse Anodic Stripping Voltammetry with Hanging Mercury Drop ElectrodeZ. R. KomyAn extraction and sensitive differential pulse anodic stripping voltammetric (DPASV) method at a hanging mercury drop electrode (HMDE) is described for the determination of Zn, Cu, Pb (mg g1) and Cd (ng g1) metal ions in water and 0.1 M HCl extracts for kakade, anise, cumin, caraway and black pepper. The procedure in water extract is based on the determination … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,880 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Cellulosic Membrane Containing Pyrrolidone Moiety Via Radiation Induced Grafting and its Application in Wastewater TreatmentA. S. Aly, H. H. Sokker, A. Hashem, A. HebeishRadiation induced grafting of vinyl pyrrolidone onto cellulose wood pulp was carried out in heterogeneous and homogenous media using gamma radiation. Cellulose wood pulp was used in different forms; a) in a homogenous solution by dissolving the wood pulp in N,N- dimethylacetamide/Lithium chloride (DMAc/LiCl) mixture , b) in a membrane form, by precipitating the cellulose solution in water and c) … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,457 accessesView PDFCite
